ZHCSQC2A November 2015 – July 2022 TPS51216-EP
PRODUCTION DATA
In auto-skip mode, the TPS51216-EP SMPS control logic automatically reduces its switching frequency to improve light-load efficiency. To achieve this intelligence, a zero cross detection comparator is used to prevent negative inductor current by turning off the low-side MOSFET. Equation 3 shows the boundary load condition of this skip mode and continuous conduction operation.
